Title: Stroboscopic light pulse detector - pulse causes thyristor to short neon tube and extinguish lamp
IPC: H04L12/26
Filed: 1973-05-04
Abstract: Pulse detectors can take the form of a whirling arm carrying a neon tube which is extinguished when the pulse arrives.

Title: Automatic multiple loaf slicing machine - takes batch of aligned loaves from conveyor and places each in vertical chute of multiple slicer
IPC: B26D7/32
Filed: 1976-01-13
Abstract: The automatic multiple slicing machine may be used to slice foodstuffs e.g. loaves and automatically transfers a batch of loaves individually into the vertical chutes of a multiple slicer. The slicer (7) gravity feeds to a distribution conveyor (8). The loaves may be fed in line on a conveyor (1) with transverse thrust walls (3) locating each loaf at longitudinal intervals. Once a batch of loaves passes onto an unloading bay the feed conveyor stops, and the batch is pushed (5) laterally onto a transfer unit (4). This has parallel walls (11) which converge to hold the loaves in alignment with the slicer chutes (6). The unit then pivots to drop a loaf in each chute (6). The slicer may utilise a double back to back band saw which traverses the base of the chutes in co-ordination with individual flap gates.
